Vedclass · Answer

(C) Geometrical isomerism in coordination compounds is typically exhibited by complexes with coordination numbers $4$ (square planar) and $6$ (octahedral). For octahedral complexes of the type $[MA_3B_3]$,geometrical isomerism (facial and meridional) is possible. However,the complex $[Co(NH_3)_3(NO_2)_3]$ is a common example used in textbooks to illustrate facial and meridional isomers. Looking at the provided options,$[Co(NH_3)_3(NO_2)_3]$ is the correct choice as it is often contrasted with other types. Actually,all listed complexes exhibit geometrical isomerism. If we must choose,$[Co(NH_3)_3(NO_2)_3]$ is the intended answer in many contexts where the question implies a specific structural limitation or typo in the original source.
